［産業上の利用分野］
本発明は中間製品の対向する両縁部に同時に縫い目を形
成するミシン装置に関するもので、特に２本の針の間に
、縫製する布地あるいはこれに類似する部材を配置する
間隙を形成したミシン装置に関するものである。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a sewing machine that simultaneously forms seams on both opposing edges of an intermediate product, and in particular, between two needles, stitches are placed on the fabric to be sewn or This invention relates to a sewing machine device in which a gap is formed in which a member similar to this is arranged.
［従来の技術およびその問題点］
本出願人は先に、間に間隙を形成し、複数枚重ね合せた
布地の両縁部を一回の縫製作業で縫うことのできるミシ
ン装置を提案した。[Prior Art and Problems Therewith] The present applicant has previously proposed a sewing machine device that is capable of sewing both edges of a plurality of stacked pieces of fabric in a single sewing operation by forming a gap therebetween.
これらのミシン装置の作動は互いに平行な両縁部を縫う
ことができるだけでなく、本出願人の完成した方法によ
り布地を引張るだけで縫製中に縁部をほぼ真直ぐにする
ことができる。The operation of these sewing machine devices not only makes it possible to sew edges parallel to each other, but also allows the method perfected by the applicant to make the edges almost straight during sewing by simply pulling the fabric.
しかし、布地によって２本の縫い目の間隔が非常に狭く
なる場合があり、また、大きな布地を２台の縫製部材の
間に形成した間隙内に垂らして配置し、所定の間隔で縫
い目を形成する必要のある場合があるため、これらの上
記のミシンにおいては２本の針の間隔をどのようにして
調整するかという重要な問題がある。これは、種々の縫
製部材は互いに適正に結合されなければならず、また、
このミシンの作業面は２個の別個の支持板に分割してこ
の間に間隙を形成する必要があるためである。However, depending on the fabric, the distance between the two seams may be very narrow, and it is also necessary to place a large piece of fabric hanging in the gap formed between the two sewing members and form the seams at a predetermined interval. An important problem in these above-mentioned sewing machines is how to adjust the spacing between the two needles, as may be necessary. This means that the various sewing elements must be properly connected to each other, and
This is because the working surface of this sewing machine must be divided into two separate support plates with a gap formed between them.
本出願人は先に２個の支持板で基部を形成したブリッジ
構造のミシンを提案した。このミシンは種々の縫製部材
に結合する軸を内包する。この内部結合軸には実際には
２本の針および関連する下側縫製部材の間隔によって軸
線方向に移動可能とするスリーブ継手が設けられている
。The present applicant previously proposed a sewing machine with a bridge structure in which the base is formed of two support plates. This sewing machine includes a shaft that connects to various sewing members. This internal coupling shaft is actually provided with a sleeve joint which allows axial movement through the spacing of the two needles and the associated lower sewing element.
実際の試験により、本出願人の提案は有効であることが
証明できた。しかし、このミシンのブリッジ構造とした

非常に精密で高価なものである場合にも、結合部あるい
は結合機構の拘束部が動かなくなる場合が多く、した・
がっで、摩耗量が多く動力の損失が大きい。Actual tests have proven that the applicant's proposal is effective. However, the entire bridge-structured frame of this sewing machine must be formed very accurately, and the connecting axes must be perfectly aligned with each other even when the sewing members are operated apart from each other. Even if the support frame of this sewing machine is very precise and expensive, the joints or restraints of the joint mechanism often become stuck, causing
However, there is a lot of wear and a large loss of power.

とのないミシン装置を提供することである。Another typical problem with these sewing machines is their high price for small-scale users. This small user
For example, there is a tendency to perform all sewing tasks on individual sewing machines of the right-handed or left-handed type, and therefore to purchase sewing machines with a bridge construction only when necessary for the actual job. Therefore, many users do not rush to buy, and do not give much consideration to the work performance, which is a feature of the above-mentioned sewing machines. - The present invention has been made in order to eliminate the drawbacks of the above-mentioned prior art. An important object of the present invention is to completely synchronize each sewing member □, to be able to move each sewing member completely and easily in the direction of each other and □, and to have a simple structure through a transmission chain. It is an object of the present invention to provide a sewing machine device in which each sewing member is not immobilized or restrained by combining the sewing members.

A sewing machine device is provided for simultaneously forming seams on both opposing sections of an intermediate product, and the sewing machine devices are arranged adjacent to each other in opposing positions, one of which is of a right-handed type and the other of a left-handed type. The machine is equipped with two sewing machines, one of which is driven by the other machine via an external drive shaft equipped with a double-structured universal joint and a sleeve-like expansion joint. It is.

。As is well known, conventional sewing machines are classified into left-handed sewing machines and right-handed sewing machines, depending on whether a gap is formed on the right or left side of the needle as viewed from the operator who feeds the fabric to the needle. When actually sewing, the operator does not need to worry about which side of the needle the gap is on, but whether it is for right-handed or left-handed sewing, as long as it prevents fabric from piling up on the back side of the machine frame. It is clear that sewing can be performed with any sewing machine, and left-handed and right-handed sewing machines are used depending on the stitches.
